Not only is it cute, Charlotte, but it's a good demonstration of caterpillar anatomy. We all know insects only have six legs, and this is true for caterpillars, as well. The three sets of legs in front that he's using to hold the food are his true legs. And that's what they generally use them for - to hold the food they're eating. The rest of the legs are called prolegs and are not true legs but are used to hold on to things. It's a trick question I like to use on kids. How many legs does the caterpillar have? I'm a little devious like that. But I figure they can use it on their teacher, friend, parents, etc. and make themselves look smart.
